printTo(string) prints numbers

Created by: burner-

String buffer = ""; root.printTo(buffer); Serial1.println(buffer); print just a numbers at esp8266 arduino platfrom. With direct serial print it works fine but that is not suitable method with webserver. Using char[] as output format looks working well String buffer = ""; char cbuf[256]; root.printTo(cbuf,sizeof(cbuf)); buffer = cbuf; Serial1.println(buffer);
